Call tracking is extremely useful metric which plugs a huge hole in conversion tracking accuracy. We use a UK based call tracking solution called AdInsight (an architel.co.uk product), which takes care of all our clients’ call tracking needs, from number allocation to reporting. We have a deal with them to get both geographical and non-geographical numbers, because many of our client prefer to have local number on their advertisements, but as far as I am aware this does not come as standard.

Best of all we use their software to dynamically change the telephone number based on the keyword search that is used for both SEO and PPC. I have not come across another company who can offer this type of in depth solution in the UK (not checked in other countries though), however their system cannot link into Google analytics like mongoose metrics does, which I think would be an amazing addition.
